Rolling bearing is a kind of rolling bearing, which is made of high quality cold rolled steel plate, sintered porous spherical bronze powder in the middle, and then rolled on the surface of porous spherical bronze powder with modified polyformaldehyde and rolled.
This type of bearing is required to be coated with lubricating grease during assembly due to its regular surface rolling arrangement and oil storage holes with helical Angle. It is especially suitable for the occasions where it is difficult to form fluid lubrication under high load and low speed. The oil storage holes on the surface can ensure the optimal oil distribution, and long-term maintenance is unnecessary.
VIIPLUS 20 series POM BUSHINGS has good physical & mechanical properties, also has certainly chemical properties. This material has good machining performance if required.tri-layer low maintanence plain bushing have a base of lower carbon steel, onto which a porous bronze layer is sintered. Acetalcopolyer (POM) is impregnated into the intersice of this bronze layer after rolling process completed. Lubrication indents are stamped into this layer.
Bronze backing with PTFE lined SF-1B Bushing , S-PM DX POM steel backed plastic covered bush , bushing FRIMIX Glyco PG A
POM composite plain bearings are available as straight bushings, washers and strips
Advantages of VIIPLUS POM composite plain bearings
• maintenance-free operation
• very good frictional properties
• high load carrying capacity
• high sliding velocity
• small operating clearance
Wrapped POM Lined Bearings Steel + Bronze Powder + POM(DX) Strips
Our POM range of wrapped acetal lined bearings are suitable for rotary and oscillating movement applications.
The VIIPLUS plain bearings are available in metric and imeprial sizes as standard.
Our in-house machining service is able to offer non-standard sizes to suit customer specific requirements.
VIIPLUS range of wrapped POM lined bearings are suitable for rotary and oscillating movement applications. They benefit from long re-lubrication intervals, no absorption of water, outstanding damping behaviors and have a low suceptibility to edge loading.
Strips PAS are available as an even material section. This material section can be used to make sliding elements in a variety
The VIIPLUS range are ideal for the automotive, machine building and agricultural industries and indeed any application where lubricant cannot be supplied continuously.
For the advantages of each group and help deciding which material group is best for the relevant use, please refer to the information provided in the section cylindrical bushes, flange liners and thrust washers.
VSB-20 Flange liners PAF
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.
Our wrapped POM lined bearings have a high wear resistance and low friction even with very small quantities of lubricant
The surface carries a pattern of circular indents which should be filled with grease on assembly
Low carbon steel gives exceptionally high load carrying capacity and excellent heat disspation
1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
